Diaphragm motion. The golden shape represents the state after muscle contraction; the blue shape represents the state before muscle contraction. a Clinical observation of the diaphragm motion and chest movement on the sagittal plane in MRI scans [24–26], b simulation results of the right hemidiaphragm for comparison with the clinical observation, c front and rear view of the diaphragm deformation, d motion of the rib cage caused by isolated contraction of the diaphragm (amplified ×2), e distribution of muscle forces based on the radial fibre orientation in the diaphragm, f simulation results of the right hemidiaphragm from simultaneous activation of the diaphragm and inspiratory intercostal muscles for comparison with the clinical observation
